Cancer epidemiologists engage in a range of activities, including: * Data Collection and Analysis: They gather data on cancer incidence, prevalence, mortality, and survival rates. This data is then statistically analyzed to identify trends and risk factors. * Research: They conduct studies to understand the genetic, environmental, and lifestyle factors that contribute to cancer. * Public Health Interventions: They design and evaluate programs aimed at reducing cancer risk in populations. * Policy Development: They provide evidence-based recommendations to policymakers to create regulations that help in cancer prevention and control.
